The Samsung Galaxy S II has been launched with the occasion of the Mobile World Congress this year and, without Samsung ever mentioning the model of the CPU driving it at launch, there were chances that the chip inside was the manufacturer’s own Exynos — also known as Orion in the past.

Well, the Galaxy S refresh will be both powered by Exynos as well as by nVidia’s Tegra 2 system-on-a-chip. The chip maker has now confirmed to ITProPortal — by showing off some slides — that the Galaxy S II was one of the Tegra 2 design wins. This should explain why Samsung was silent about the make and model of the CPU powering the smartphone (and still is by listing a generic Samsung Dual Core Application Processor with a bottom note that it “may not be applicable in some regions”).

We already figured out that the Galaxy S II will be shipping with two different types of CPUs once they appeared in the benchmarks: Samsung’s model GT-I9100 with the Exynos 4210 CPU aided by the Mali-400 MP GPU and model GT-I9103 powered by nVidia Tegra 2, running a ULP GeForce GPU. The questions left unanswered as of yet are whether there will be a price difference between the two and what version will go to which region?
